Test Principle

Caps shall permit a min. air flow of 8 l/min, measured at roomtemperature, with a max. Pressure drop of 1.33Kpa.

0.1-0.2 MPa air flow into the BS7272Ventilated Caps Air Flow Tester, cap after decompression, under the pressure of0.1 MPa;

After decompression, around 40 kpa pressure control, access to theflow meter for the ventilation test cap.
